Product Q&A
67 QuestionsQ: I have read in other spec sheets online that this product is suitable for use with domestic water as well as heating applications. Is this true or just a rumor? We would like to use this product in an "open" heating system.

Verified Reply- PexSupply StaffSome brands of PEX-AL-PEX are approved for use with potable water, but the Rifeng tubing is not. This tubing would be fine for use in an open system, although the oxygen barrier is not really necessary.
Verified Reply- PexSupply StaffYes, PEX-AL-PEX pipe is suitable for use with plumbing system and heating system. Because there is aluminum core in the middle of PEX-AL-PEX pipes, they can reliably prevent oxygen from permeating into pipes. Yes, you can use this in an open heating system. Keep in mind, to prevent rusting, you should have a bronze or stainless steel circulator, not cast iron.
The tubing itself can be used for domestic hot water, but the problem is that it requires special fittings that are different (and more expensive) from the regular PEX fittings. For radiant heating, the only connections are usually at the manifold, so you just get the special fittings for the manifold. But, if you use it to run water to the whole house, then you will need special PEX-AL-PEX fittings everywhere.
Q: Can I use the copper clamp with this probuct or do I need to use the stainless clamp?
Asked by bert 14 years ago

Verified Reply- PexSupply StaffPEX-AL-PEX tubing does not have the same dimensions as standard PEX tubing. PEX-AL-PEX only works with compression and press fittings designed for PEX-AL-PEX. It is not compatible with copper crimps and stainless steel clamps.
I didn't use any of them i used the watts compression fittings that have a double o ring that goes on the inside of the tubing and a compression ring that goes on the outside to lock it in place
Q: What is the minimum bend radius for 1/2 inch PEX-AL-PEX?
Asked by Ed 14 years ago
Add your answer
Verified Reply- PexSupply StaffRifeng 1/2" PEX-AL-PEX has a minimum bend radius of 3.15".
It bends quite easily. If you are careful, and use a bending tool to support the bend as you make it, to help prevent kinks, you can make a 180 degree bend in 6 inches or even a little less if you don’t' mind pushing your luck a little. So a 6 inch diameter arc would be a 3 inch radius. Use a piece of scrap to practice on for making sharp bends. After a few tries you will get a good idea of how far you can go. If you don't have a bend tool, you can use a piece of round PCV pipe to support the bend. If you try it with just your hands, without any support, it is more likely you will kink it.
the tightest bed i have ever made with the stuff was close to 8" radius by hand. if you use a bender i'm sure it can go tighter.
Q: I am planning to install radiant floor heat in a slab. Other than price, while looking through the specs, I see no significant difference between the standard oxygen barrier pex, the therma pex, the hepex plus and the pex-al-pex (other than the obvious alum. layer which eases in installation but requires other fittings). Which is the recommended product for my application?
Asked by Construction Genius Extraordinaire???? 14 years ago

Verified Reply- PexSupply StaffPEX-AL PEX tubing has the advantages of increased rigidity and less linear expansion, but there are fewer options for fittings. hePEX and ThermaPEX differ from most oxygen barrier PEX because they are graded PEX-A. PEX-A has superior shape memory, making it more flexible, more freeze-resistant, and easier to work with. You can fix kinks in it by applying heat, and only PEX-A works with expansion type PEX fittings.
Go with the one you like the best. I like the Pex al Pex but the fittings get real expensive if you need a lot of them.
Q: Are the fittings the same for different types of Pex 1/2"

Verified Reply- PexSupply StaffThe fittings required for PEX-AL-PEX tubing are different from the ones you need with standard PEX (i.e. PEX without an embedded layer of aluminum). With PEX-AL-PEX, you're limited to certain press and compression fittings.
No.different types of pex require different fittings.some pex also require you to prep the tube(strip the outer jacket and or bevel/chamfer the edges) before assembly.
No. You have to use the fittings that are designed to work with your particular PEX. Some fittings will work with different types but not all. Consult with the manufacturer of the PEX you are using to insure you have the correct parts.
I have not used the ½", so I can't really say, however, if the same logic fits for the ¾", they are different. The OD for the Pex-AL-Pex is larger due to the layer of Aluminum, besides the fittings for Pex-Al-Pex we all compression, not crimp. Thanks Scott Valare
The fittings for Pexlex are different from regular PEX. You need to use fittings specially degd for Pex-Al-Pex.
Everything I found says that you cannot use the ring crimp type fitting (like the ones at Menard's) but I have used them on 10 or so connections and they work perfectly. They pressure tested ok up to 100psi and have been in use for 2 winters with no problems. Please let me know if you find other to back this up or have information as to why the say they should not be used. Peter
No , PEX-AL-PEX fittings are different than regular PEX connectors. Don't try and use crimp type fittings. PEX-AL-PEX uses O-rings to seal the connection.
The fittings for Pex tubing change based on two scenarios. One scenaro is the type of Pex tubing being used. If you use a Pex Al Pex tubing (aliminum barrier) then you must use a Pex Al Pex compression fitting. However, if you are using potable non-barrier tubing or an oxygen barrier Pex tubing then you can use 3 diffenant types of fittings it just depends on what tool if any you plan to use. If you are using a Crimp tool then you can use the HydroPex crimp fiittings in conjunction with copper crimp rings or stainless steel clamps. If your using a expander tool then you can use the ProPex fittings in conjunction with the expander rings. If you choose to use no tool at all then you can use a push to fit fittings.
We have used pex/al/pex pipe and fittings for a lot of years, and those fittings generally can be used on any of the pipe, we just look at the ID and OD With the pex tubing, as long as the inside diameter and outside diameters are the same you should have no problem interchanging the fittings. We have tried the pex/al/pex fittings on pex tubing and the 1/2" size works, but not on the 3/4" or 1" sizes. You have to get pex fittings.
Q: i need to buy a chambering tool to get compression fittings to work at heat manifold?
Asked by 14 years ago
Add your answer
Verified Reply- PexSupply StaffA chamfering tool is recommended for use with PEX-AL-PEX prior to making a fitting connection. The tool creates a beveled edge on the inside of the tubing so that the o-ring sets properly.
Q: Does this brand of Pex al pex have a oxygen barrier?
Asked by 14 years ago
Add your answer
Verified Reply- PexSupply StaffThe aluminum barrier in this PEX-AL-PEX tubing serves as the oxygen barrier. This is true of all PEX-AL-PEX to our knowledge.
Q: What do you do if you inadvertently put a kink in the tubing during installation?
Asked by Steve 14 years ago
Add your answer
Verified Reply- PexSupply StaffWith PEX-AL-PEX you would need to cut the kinked portion of the tubing and insert an appropriate fitting at that location. It cannot be repaired with a heat gun as PEX-A tubing can be.
Q: What is the inside diameter of the 1 inch pex-al-pex tubing? You would think 1 inch, yet It appears to be slightly larger than 1 inch and is larger in diameter than the 1 inch regular Pex. I want to be sure that the Pex-Al-Pex 1 inch fittings will work.
Asked by 14 years ago
Add your answer
Verified Reply- PexSupply StaffThe listed size for PEX-AL-PEX tubing corresponds to its inside diameter. PEX-AL-PEX has a larger ID than standard PEX (1" standard PEX, for example, has a .862" ID). PEX-AL-PEX is only compatible with compression fittings and press fittings that are designed for use with PEX-AL-PEX.
